ABSTRACT:
A control mechanism for use with a fluorescent lighting unit having at least first and second lamps utilizing a line switch. The mechanism includes an AC toggle which alternately interrupts and connects electrical power from a source to one of the first and second lamps, only. The toggle is responsive to the successive opening and closing of the line switch. A reset feature overrides the means for alternately interrupting and connecting power source to one of the pair of lamps by connecting power from the source to the second lamp. The reset feature is also responsive to the operation of the line switch.
